Application filed December 29. 190 4:- Serial No. 238,802.

To atZZ whom it may concern:

" Be it known that we, JOHN J. .MOLAUGHLIN' and JOHN REsNER, citizens ofthe United States, residing'at Scotland, in the county of 'Bonhornme andState of South Dakota,have invented certain new and useful Improvementsln'Sulky Attachments for Harrows, of which the following is aspecification.

' This invention relates to agricultural implements, and embodiesanattachment designedchanging the position of the attachment .relativeto the harrow in order to avoid obstacles which may be located in thepath of travel of the implement. Z

. For a full description of the invention and the merits thereof andalso to acquirea knowledge of the details of construction-of the meansfor effecting the result reference is to 3 be had to the followingdescription and accompanying drawings.

While the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features thereof,

still the preferred embodiment thereof is shown in the accompanyingdrawings, in wh1ch Figure 1 is a perspective view of anattachmentembodying the invention. Fig. 2 is a vertical longitudinalsectional'view of the attachment. Fig. 3 is a plan View, the harrowjconstruction being shown in dotted lines. Fig. 4 is a detail perspectiveview showing the actuating-bar by which the position of the atreferencecharacters.

The attachment mainly comprises a suitable supporting-frame ofapproximately rectangu- PatentedSept. 26, 1905.

lar' formation, as indicated at 1 in the draw- 1.

vings. Thisframe 1 is mounted upon casterwheels 2, located adjacent therear end of the frame at opposite sides thereof. A suitable seat 3 forthe operator is provided upon the frame 1, said seat beingcarried by arear- {wardly-extend'ing standard 4:, braced at 5. The

front end 'of the standard 1 extends down- Qwardly and is secured to thefront portion of the frame 1in a manner which will be readily apparent.A vertical, supporting member 6 also braces the member 4 adjacent itsfront end, and this vertical member 6 has pivoted thereto a plurality offoot-levers 7 and 8, de-

';signed to actuate the sections of the harrow in effecting properadjustment of the latter. he foot-levers 7 and 8 are of bell-crank for-;mation, having lateral extensions against jwhichthe operator may placehis feetin order ;to actuate the same.

The front of the frame 1 carries a plurality of vertical arms 9, inwhich are mounted a Iplurality of rock-shafts 10 andv 11, the shafts,111 being disposed above theshafts 10,and all of the shafts are carriedin suitable bearings upon the arms 9;aforesaid. The shafts 10 and ;11are provided with crank-arms 12, and the uppermost shaftsll areconnected by links 13 withthe foot-levers 8, whereas the crankarms 12ofthe lowermost shafts 10 are likewiseconnected by members, 13 with thefootlevers 7. The crank-arms 12 are located at the adjacent extremitiesof the rock-shafts 10 ,and 11, so that jthevariou s connections betweenthe shafts and foot-levers are assembled icentrally of the frame 1, thusgiving com- 'pactness and rigidity to the parts. Each of the rock-shafts10 and 11 is supported adjacent its outer end by means of abearing-plate 14:,pendent froma truss-rod 15, which passes through theupper ends of the end arms 9. The rod 15 is utilized to brace the arms 9and 'toafford a support for the bearing members 14 aforesaid. V Therock-shafts 10 and 11 are I connected each with a single section of theharrow,;lj'(indicated in dotted lines in Fig. 3,) land for. this purposea rock-arm 16 is carried by each shaft 10 and 11,said rock-arm beingadjustable longitudinally of its respective shaft and connected with arespective harrowsection, towhich it is attached by means of a flexibleconnection 17, such as a'chain or the like. The adjustability of therock-arm 16 prising the invention is thus made susceptible ofapplication to harrows of different sizes. The rock-arms 16 are held inadjusted position by any desirable means, such as set-screws or thelike.

From the foregoing it will be noted that at the will of the operator,who is seated upon the seat 3, any one of the foot-levers 7 and 8 may beactuated in order to thereby tilt the respective rock-shafts 10 and 11with which it is connected. A tilting movement of any one or more of therock-shafts 10 and 11 will impart a rocking or pivotal movement'to thearm 16 carried thereby, and since this arm is connected by the part 17with an ascertained section of the harrow it will be clear that suchsection may be raised or lowered in order to throw it out of operationtemporarily or to drop material which may clog the harrowteeth andprevent perfect working of the implement.

The attachment is connected with a draftbar 18 of the harrow by means ofacentrallyconnected bar 19, secured at its front end to the draft-bar 18at a point between the ends of the latter and attached at its rear endby a swivel connection 20 to the standard 4, projecting upwardly fromthe frame 1. The rod or bar 19 affords the main connection between theattachment and the barrow. However, rods 21 are utilized to afford afurther connection, said rods 21 being attached at their forward endsnear the ends of the draft-bar 18 of the harrow, and the rear ends ofthe rods 21 are pivotally secured to the actuatingbar 22, pivoted to theframe 1 of the attachment, as shown at 23, at a point between its ends.The actuating-bar 22, which is connected at its ends to the rods 21, isadapted for pivotal movement upon the frame of the attachment, andguides 24 are arranged longitudinally of the side bars of the frame 1,so as to receive the actuating-bar 22 near its ends and direct itsmovement in a horizonal plane.

An operating-lever 25 is pivoted to one side of the frame 1, as shown at26, and this lever 25 is provided with a latch device 27 of commonconstruction, cooperating with a segment 28, attached to the frame 1 inany substantial manner. The lever 25 projects downwardly from the pointof pivotal connection 26 thereof, and its lower end is connected bymeans of a link 29 to the actuating-bar 22. (See Fig. 4: of thedrawings.) A pivotal movement of the lever 25 is designed to impart asimilar movement to the actuating-bar 22, and such movement of thelatter, owing to the positive connection of the frame of the attachmentwith the draftbar 18 of the harrow, will throw the attachment to oneside or the other, so that any obstacles which may be located in thepath of travel may be readily avoided at the desire of the operator.

The attachment hereinbefore set forth is comparatively simple inconstruction and admits of ease of operation of the sections of theliar-row not heretofore attained by devices of this nature now in use.Further, the attachment is designed for use upon almost any type ofbarrow, being broadly susceptible of application to implements of thisclass.

Having thus described the invention, what is claimed as new is 1. In anattachment of the class described, the combination of a supportingframe,a transverse draft-bar, means connecting the draft-bar at a pointbetween its ends with the supporting-frame, a transversely-1nountedactuating-bar carried by the supportingframe, rods connecting the endsof the actuating-bar with end portions of thedraft-bar, and a leveroperably connected with the actuating-bar.

2. In an attachment of the class described, the combination of asupporting-frame, longitudinal guides at opposite sides of thesupporting-frame, a transverse draft-bar, a transverse actuating-barmounted in the longitudinal guides of the supportingfra1ne, connectingmeans between the ends of the draft and actuating bars, other connectingmeans between the supporting frame and the d raft-bar, and means foroperating the actuating-bar.

3. In an attachment of the class described, the combination of asupporting-frame provided with spaced longitudinal guides, anactuating-bar pivoted to the supporting-frame at a point between itsends and having its end portions mounted for movement in thelongitudinal guides aforesaid, a draft-bar arranged transversely of thesupporting-frame, rods connecting the ends of the draft and actuatingbars, a lever pivoted to the supporting-frame and operably connectedwith the actuatingbar, and means for positioning the lever at anascertained adjustment.

1. In an attachment of the class described, the combination of asupporting-frame embodying supporting-wheels, an actuating-bar mountedtransversely upon said frame, a draftbar, connecting means between theend of the actuating-bar and the draft-bar, and means for impartingpivotal movement to the actuatingbar.

In testimony whereof we afiix our sign atures in presence of twowitnesses.
